Optimal harvesting in a two-species model under critical depensation: The case of optimal harvesting in semi-arid grazing systems

Ecological systems in general often exhibit the mechanism of critical depensation, i.e. the system may collapse due to decreasing population densities caused by, for example, an increasing predation pressure on the prey that causes both populations to collapse to extinction. In this study a semi-ari...
